VV. M. CADY AUTOMOTIVE BRAKE Filed March 10. 1924 in @im e AUTOMGTVE To f/ZZ 'wim/11. t may renfe/1n.'

Be i1V known 'hzit i` iinninr M. Mm'. n Citizen of the United' Sintes. residing in Ildgewood. in the eoun'zy o1c Allegheny and Siate of Pennylvnnia, have invented :i Certain new :ind nsefni in'ipiofenien. in Anh motive Brakes, of whieh the 'foiowing is a specifi tation.

This inveniion reime?, to brakes, :1nd more particularly to n fnnid pressure from' wheel brake for motor vehicles.

The -ik'nineipai object of 'my invention to provide nnin'ipi'oved 'ln-ske of the above ehni'neei.

in the :ieeonipnnying diuwing; Fig. l. is :l ceni'nl sectional view of n inid pressure front wheel brake embodying my invention: and Fig. 2 :i section on the 'line 2-2 of Fig. 1.

in Fig. l in shown n portion 1 of a vehieie iiont wheel and iie usual. steering' knuckle 2 for supporting he front Wheel. hi'nke di'mn 2) is secured to the 'front Wheel :1nd is inovided with n Cover plate 41 having e een'ini depifesszion 5 for ieeeivinfy vthe knuckle Pivoniiy connected brake needs (3 ziie mounted within he drinn 3 and are i-iiovided n''h hinke Shoes 7 adapted, to engage the. infermi frielioii fune '8 of ihe drinn 3.

.fienoiwiing' if in v inveniim, the upper wall 9 oi' the depression 5 is foimed io pro vide a brake ehninhei', e eovei plate .10 being provide-'L having :in :innnim' fiange for Securing; seine to the Wall lntei'pesel between the Waiil or brake chanihei 9 land the 'cover plate l() is a Flexible diaphragm 1l having' n pressure plate 12 engzigg'ing'ione .Side and having the ehambei ai'. the other side open te e iuid pressuie sin ply and release pi e 13.

Links M, pivea 1y connected to the free ends of the brake heads 6, are pivoaiy connected to a erosshead 15, secured ivo n diaphragm rod 16, which is carried hy the piessne plate 12.

wWhen iinid under pressure is supplied through 'pipe 13 to the diaphragm H, said diaphragm is inoved'npwardly, operating? the rod 16 so that the' links le ect to spree the ends of the brake heads 6.

The beke heads 6 are thus expended, causing the brake shoes 7 to frictienniiy ein gage. the internal friction face of the ineke drinn and thus effect an application of the brakes.

By 'forming the brake chamber in the cover plate 4 and in the upper Wall of the depression 5, n compact construction is provided, wherein the brake eha'rnhei is Wholly contained Within the brake drinn.

'Having new described my invention, what claim :is new and desire to secure hy Let ters Patent, iszy The eomhinationwih e brake drum and brake heads inonned in Said drum, e?? n cover 'piae foi. said drum having e eentei. depression extending ine Said drum, one 0f the Side Waiis of seid depression having n brake. chamber formed therein, und n movv able abutment in said' chmher operatively connected to said brake heads.

in testimony whereof have hereunto Set my hand.V
